In order to make bootparams and /tftpboot more static,
I tend to jumpstart both 2.5.1 and 2.6, booting 2.6 only.
So far I've been quite successfull with passing the target
OS rev via boot args (boot net - install 2.5.1 desktop)
and modifying .cdtoc correspondingly on the fly in order
to pick proper media. I also had to add SUNWswmt to 2.5.1
.clustertoc to do latest patches properly in finish scripts.
Naturally, I can't use "uname -r" anymore in finish scripts,
but that's OK, I can fetch it from target kernel in /a
That's all the problems so far, new heterogeneous jumpstart
seems to work allright. I just wonder whether there are any
issues that I've overlooked, or maybe some issues will
arise later when I'll boot 2.7 to jumpstart 2.5.1 and 2.6
Thank you for any hints.
